TOOL.

Application filed September 2, 1924. Serial No. 735,441.

This invention relates to a tool and especially to a tool adapted to be used as a spanner wrench.

An object'of the'invention is to provide a simple spanner wrench provided with means whereby it can be used for several other purposes as well.

Another object concerns the provision of a tool which is simple, durable and efiicient and especially adapted for use by members of fire departments.

The invention is illustrated in'the drawings, of which- Fig. 1 is a plan view of the device;

Fig. 2 is a plan view partly in section;

Fig. 3 is a side elevation partly in section; A

Fig.

4t is a partial side elevation; and

Fig. 5 is a front elevation.

The form of the invention shown in the drawings is a preferred form although it is understood that modifications in the construction and arrangement of the parts and in the character of the materials used may be adopted without departing from the spirit of the invention as set forth in the appended claim.

In its general aspect the invention concerns a tool which can be used by members of the fire department as a cold chisel, as an ordinary wrench, and as a spanner wrench.

Another aspect concerns the provision of a new and improved socket on that part of the tool which is used as a spanner wrench whereby the engagementof the socket with the stud to be turned is made more effective.

In a further aspect of the invention it is provided with a nut-engaging socket or aperture so formed as to be capable of engagement with more than one size of nut. As shown in the drawings, the preferred form of the invention includes a tool having a stem or body portion 1 on one end of which an enlarged head 2 is provided with r a curved front face 3. In this front face are provided two rectangular openings 4 and 5 having straight edges and adapted to act as spanner wrench sockets to engage projecting studs or nuts on the collar to be moved by the action of the wrench. The

inner and outer walls 4* and 5 of the open ings 4 and 5 are inclined to and in the same direction of the longitudinal axis of the body 1, the inner walls of said openings terminating at the face 3 a short distance apart, forming a central bearing surface 2 which extends from one side of the head to the other, as shown in Fig. '5. sides of these sockets or openings thus constructed, the engagement with the stud or nut is found to be more effective. By forming the face'3 with openings, as described, a large bearing surface for the face. is also provided.

There is also provided in the head portion 2 a. wrench socket or opening 6. This is square in section and its walls are tapered so that at one end the socket is adapted to engage a nut of one dimension, and at the other end is adapted to engage a nut with another dimension, with the possibility, of course, of engaging nuts of intermediate dimensions.

On the other end of the tool the stem is provided with a chisel portion 7 so that a fireman when using the tool can use this end as a chisel or jimmy to pry open sashes, doors, skylights, etc., in an emergency.

It will be obvious, therefore, that this particular tool adapts itself to a variety of uses and is simple, eflicient, durable and compact. It may be made, of course, in any size and shape and of any particular material without departing from the spirit of the invention.

What I claim is A tool of the character prising a handle provided at one end with a head having a curved front face provided with two rectangular openings, the inner and outer walls of the openings being inclined to and in the direction of the longi- By having the described COHI- tudinal axis of the handle, the inner walls of said openings terminating at the front face a short distance apart on opposite sides of the-longitudinal axis of the handle and forming a central bearing surface for the face which extends from one side of the head to the other.
